Hi,
This patch set introduces one process flag and trys to fix one deadlock
problem on block device during runtime resume or usb bus reset.
The 1st one is the change on include/sched.h and mm/page_alloc.c.
The other 2 patches are applied again PM and USB subsystem to demo
how to use the introduced mechanism to fix the deadlock problem.
